(i) Two human activities which are responsible for the process of soil erosion are deforestation and overgrazing, mining, construction, etc.

(ii) Types of Soil Erosion:

(a) Cullies: The running water cuts through the clayey soil and makes deep channels/gullies. The unfit land caused by gullies is called bad land or ravines.

(b) Sheet erosion: Water flows as a sheet over large areas down a slope. The top soil is washed away. This process is known as sheet erosion.
